Hello,
When importing dxf files, how do you get mach 2/3 to compensate for tool diameter?, how do you get it to know if the profile yoou want to cut should be cut from the inside or the outside?
I guess one way arount it is to offset the geometry in a cad program so the new geometry follows the center of the tool, instead of the outline of the geometry you want cut.
Regards

You are going to have to draw the lines to offset for the tool in your cad system OR you can try to code in a comp move by hand (This is NOT simple!).
Hope that helps

I also am in a similar situation knowing very little about cam . I recently built a machine modelled after Joe's 2006 designwith minor mods .
I am currently finishing assy of a "hobbycnc" controller, all being well that should be finished this coming week.
So I will most likely try the trail version of Mach3. Through osmosis I know that the machine and solftware should be able to produce from a DXF drawing .I have produced a DXF drawing of a fret I would like to make .
The problem the fret has several levels and the drawing is basically two dimensional . How does one program the machine to machie the fret to the required levels. Do I need to redraw the drawing designating each level as a separate layer ?..... appreciate any help
